I have been using a DOS-73 board in my 7300, and have been very pleased
with it.  Everything that limits itself to standard DOS system calls
seems to work fine, and I have had little or no problems with software
that uses ROM BIOS calls.  I have successfully run several C compilers,
editors, spreadsheets, and many utilities, even TSRs such as CED and
pop-up desk accessories.

The only things that have failed to work are those that try to go out and
access the PC hardware directly.  This category includes games like
flight simulator, and TSR clock programs.

The display works by simulating a Hercules graphics card, so you may
have problems with software that doesn't support Hercules mode though, again,
anything that uses DOS for its screen access should work fine.

If you have any package that might be questionable and you plan to use
it on the 7300, I would suggest locating a system with a DOS-73 card
and trying it out before you buy one.
